【摘要】：本文在LEO衛(wèi)星簡(jiǎn)化動(dòng)力學(xué)和SLR檢核的原理基礎(chǔ)上,利用Bernese5.2軟件實(shí)現(xiàn)LEO衛(wèi)星簡(jiǎn)化動(dòng)力學(xué)定軌和軌道檢核。將Bernese5.2軟件定軌結(jié)果與Bernese5.0軟件進(jìn)行對(duì)比,單點(diǎn)定位軌道精度提高了30~40cm,觀測(cè)值組合定軌在徑向、切向和法向上均提高了3cm左右.將定軌結(jié)果與GFZ科學(xué)軌道進(jìn)行比較,利用Bernese5.2解算的衛(wèi)星軌道其擬合精度更高,徑向、切向和法向均優(yōu)于3cm.利用SLR檢核LEO衛(wèi)星軌道,其視向精度優(yōu)于3cm.
[Abstract]:On the basis of the principle of LEO satellite simplified dynamics and SLR check, this paper uses Bernese5.2 software to realize LEO satellite simplified dynamic orbit determination and orbit check. Comparing the orbit determination results of Bernese5.2 software with that of Bernese5.0 software, the accuracy of single point positioning orbit is improved by 30 ~ 40 cm, and the observed value combination orbit determination increases about 3cm in radial direction, tangential direction and normal direction. The results of orbit determination are compared with that of GFZ scientific orbit. The satellite orbit calculated by Bernese5.2 has higher fitting accuracy, and the radial, tangential and normal directions are better than 3 cm. Using SLR to check the orbit of LEO satellite, the apparent direction accuracy is better than 3 cm.
